Hormonal stimulation

Hormonal stimulation, which causes a higher number of eggs to mature in the woman’s ovaries than in a natural cycle, is part of every IVF cycle.

We start the stimulation on the 2nd to 3rd day of the menstrual cycle, and it lasts altogether 10 to 12 days. The application of stimulation drugs is not complicated. A nurse will help you with the first dose, and then you can easily manage the subsequent doses yourself at home.

For stimulation, we use only modern medications that are gentle on your body and that increase the success of the entire treatment.

During the stimulation, you will have regular check-ups where the doctor will use ultrasound and blood tests to check that everything is going well. You can have the ultrasound examinations at your local gynaecologist or at our clinic.

For many years, we have been using the high-quality medication Gonal F for hormonal stimulation. It is administered in the form of a pen and is popular for its convenient application and high effectiveness.

Most frequently asked questions

Does hormonal stimulation have a negative impact on the body?
The greatest hormonal burden on a woman’s body occurs during pregnancy. During hormonal stimulation associated with IVF treatment, hormone levels reach only a fraction of these values. If a woman’s stimulation is managed correctly, it does not have negative effects on the body.

What is ovarian hyperstimulation syndrome (OHSS)?
We refer to an excessive ovarian response to hormonal stimulation as OHSS (Ovarian Hyperstimulation Syndrome). This condition is characterized by abdominal pain, which is caused by the enlargement of the ovaries and the accumulation of free fluid in the abdominal cavity. Symptoms such as nausea, vomiting, and diarrhea may also occur. Regular and careful monitoring throughout the entire stimulation process is essential in preventing the development of OHSS.

How often does Ovarian Hyperstimulation Syndrome (OHSS) occur?
With the development of modern stimulation medications, the risk of Ovarian Hyperstimulation Syndrome (OHSS) has significantly decreased. Now, these cases occur in fractions of a percent.

Are stimulation and hormone injections painful?
Injections using a pen are administered subcutaneously (similar to insulin) and are not painful. Towards the end of stimulation, you may feel some pressure in the lower abdomen, similar to what you might experience before menstruation.

Why do supplementary payments for stimulants vary so much?
In addition to recombinant preparations, which are produced in the laboratory, there are also preparations of urinary origin, which are obtained from the urine of menopausal women.
These are highly purified drugs, but they do not guarantee the quality of stimulation with the reliability and accuracy that we want to offer at our clinic. Although the additional cost of urinary preparations is an order of magnitude lower, no clinical study or our experience has yet convinced us to recommend urinary preparations as a first choice.

Which day is the first day of the cycle?
This is the first day of menstruation, i.e. heavy menstrual bleeding. Light bleeding is not considered the beginning of a cycle. If you start bleeding in the evening after 8 p.m., then the next day is considered the first day of menstruation.

Why do I have to go for check-ups during stimulation?
Your body’s response to stimulation can be individual – depending on your age, weight, egg supply and type of stimulant. That is why we monitor everything closely during the process. At check-ups, the doctor checks the ovary response with ultrasound scans and, if necessary, takes blood samples to check hormone levels.
